Toe box needs improvement.

Three and a half really. I purposely bought 1/2 size larger to give my hiking toes more room. However the toe box is still tight while the heel is loose and the boot top loosely rubs my skin with walking. Still breaking them in with hopes they mold better to my foot. Loved my similar old pair that lasted over a decade!
